The OXO Good Grips Prep & Go 3.3-Cup Container will be your new go-to for meal prep, lunch, or leftovers. Whether you’re packing up the rest of tonight’s soup, meal prepping veggies, or making a grain bowl for tomorrow’s lunch, this container is up for the job. You can even microwave everything in the container and the stay-cool handles will make for easy transport to the table or your desk. The watertight lid with silicone seal and locking clips ensure leakproof travel, whether you’re taking the container from the fridge to the microwave or all the way to work. For a secure seal, press firmly in the middle of the lid, then engage the latches; you'll hear air being released as you press the lid down. Once you’ve released all the air, lock the latches on the side of the container to seal. To replace the gasket, press the four corners down, then press the rest of the gasket into place, ensuring the gasket is pressed down fully and evenly. OXO Prep and Go Containers stack neatly on top of each other for efficient and tidy storage either in the fridge or in your cabinets. Although it looks like a sleek, ceramic container, it’s actually a much lighter, BPA-free, durable alternative to single-use plastic. Dishwasher, freezer and microwave safe. The containers are also odor- and stain-resistant, and shatterproof.
